SHUTTLE-OLEfhRING MEANS FOR FILLING-REPLENISHING LOOMS.

Application filed. July 16,

QUIST, a citizen-0t the resident of Manchester, county of Hills borough, State of New'Hampshire, have invented an Improvement in Shuttle-Clearing Means for F 1lling-Beplenishing Looms, of which thefollowing description, in connection with the specification, like characters on the drawing representing like, parts.

his invention relates to improvements in fillingend clearing mechanism for automaticfilling replenishing looms andthe object is to provide an effective mechanism which will engage and clamp'positively the filling end running from a discharged filling carrier so that the removal of said filling end from the shuttle will be insured.

In the operation of automatic filling replenishing looms the running filling is replenished from time to time by the insertion of a fresh filling carrier into the running ejecting therefrom the filling carrier from which the filling is more or less exhausted. .old filling carrier is thus ejected from the shuttle a trailing filling end extends through the shuttle .eye which must be removed in order to clear the shuttle eye for the fresh filling and also toprevent the trailing filling end from being carried by the shuttle into the shed. r a

I an aware that various means have been provided for clearing the filling end from tor example as that dis February 13, 1906.

The object of the present invention is to provide an improved mechanism for accomplishing this purpose comprising a filling end clamping means which will be opened during the initial action of the transferring before the lay beats up againstthe tell of the cloth and which will engage andclamp the filling end of the discharged filling carrierduring the final portion of the movement of the transferrer so that thefill- Ting end will be securely clamped before the shuttle is picked after transfer, thereby insuring the withdrawalof the old filling end,

v preventin r with certainty the drawing of the filling endinto theshed. i FA'inrther object of the invention is to accompanying drawing, is a When the actuating the filling 1921. Serial No. 485,276.

provide means for locking clamping means in closed position during the normal operation of the loom and means operable, preferably from the dog of the transferrer, for unlocking and permitting the opening of the filling end clamping the filling end 'means as the dog is moved into operative position.

A further. objectot the invention is to provide means operated by the transt'errer arm to restore the filling end clamping means to locked position during the final movement of the transferrer arm.

A further object oi the invention is to provide yieldable means for actuating the filling end clamping means which will prevent breakage of said clam 'iing means if any obstruction intervenes between the jaws;

of the clamping means.

'A. further object of the invention is to provide a novel form of clamping means comprising a stationary jaw extending in a direction normal to the longitudinal axis of the lay and having an end extending in parallelism with the axis oi the lay, adapted to insure the catching of the filling end, with a movable jaw so mounted as to be moved transversely across the path of the filling end running from the shuttle to the discharged filling carrier.

Other objects and features of the inven tion will more fully appear from the folldwing description and the annexed and will he claims.

Fig. 5 is a side elevation of the means for end clamping means drawings pointed on}; in the accompanying illustrated in'Fig. a.

The present invention is designed to be embodied in or applied to a usual type of,

fresh filling carriers. The filling carriers are transferred from the hopper to the shuttle 4 which is carried b the lay 5 by a transferrer 6 havin a hea 7 adapted to en age the basesof t e filling carriers, and force 'them from the hopper into the shuttle,

engages the tip ing and thereby causing; the incoming filling carrier to eject the old filling carrier from the shuttle. The transferrer arm 6 is pivotally mounted upon a transferrcr stud 8 which is carried by the hopper stand 2 and is provided with a downward extension 9 on the lower end of which a dog-supporting member 10 is ivotally mounted which carries a dog 11 adapted upon transfer to be positioned in the path of the hunter 12 carried by the lay 5.

The dog 11 is provided with a stud 13 which engages a cam slot in the usual arm 14 which is connected to the shuttle feeler and is operated through an arm 15 upon the controller rod 16.- The controller rod 16 may be actuated as is usual either by the feeler mechanism or the weft fork mechanism of the loom, or both.

The transferrer stud has secured to its end an arm 17' upon the end. of which a :holder 18 for the tip of the bobbin is yieldably mounted. The transferrer arm is also provided with a tip engaging member 19 which, upon actuation of the transferrer, of the bobbin at the same time the trans errer head 7 engages its base. The member 19 thus serves to guide the tip of the bobbin during the transfenof the bobbin from the hopper into the shuttle.

The mechanism thus described may be and is a usual type of construction and, therefore, need not be further described.

The present invention contemplates the provision of novel means, preferably supported upon the transferref stud, for catchclamping the filling end from the ejected bobbin immediately after the bobbin has been discharged from the shuttle and positively holding the same" until transfer is again called for. By reason of this construction the withdrawal of the trailing filling end from the shuttle eye is insured andrthe ossibility of said trailing end'heing whipped into the shed is effectively prevented.

In the preferred embodiment or the invention the filling end clamping means comprises a bracket 20 which is secured t upper end to the arm 17 of the tip su}. ing member andnt its lower and is pi with an offset horizontal extension 21 ing the stationary jaw of the filling clamping means. The horizontal ex or stationary jaw extends in a direction mail to the longitudinal axis of the l adapted to enter the usual cutaway of the lay which is located. below the box.

The stationary jaw 21 desirably is provided at its end with an integral late; extending portion or finger which extends substantially in parallelism with the longitudinal axis of the lay and is adapted to prevent the filling from being thrown bcyond the end of said stationary iaw.

The stationary jaw desirably is provided with a facing 23, of leather or other trio tional' material, adapted to co-opcrate withv the movable jaw to more firmly engagethe filling end.

The filling end clamping means comprises also a toothed movable jaw 24: adapted to so cooperate with the stationary jaw 523, said movable jaw 24 preferably being pivotally mounted upon a stud '25 projecting up wardly from the elbow of the brac F20. The movable jaw is provided with a later-- ally extending boss or arm 26 which is engaged by a preferably resilient member it? which is curved at its opposite end and an chored to a stud 28 which may be'adjust ably mounted in the offset end of aetusting lever 30. The actuating lever 30 is pivotally mounted upon a stud 31. carried by a bracket 32 which has upon. its upper end a boss 33 which is mounted upon the transferrer stud and is secured ri 3.05 position upon said stud by spring 35, engaging at one lever 30 and at its opposite e against a boss 36 upon the or mally tends to force the end o which is connected to the movable in a direction as to more e jaw the clamping means to open pot. ion.

Means preferably are provided, hot for normally locking the jaw. 'durh. operation of the loom, in cl pa As illustrated herein this is .cemol by a detent lever 3? which is mounted upon a screw or stud tlTi bracket Qne arm. of so lever has a shoulder 39 which cng lever 30. The other arm ill of said lover is provided with a cam face ion. its nder side. A spring intcrpo. arm 40 and en abutment upon 32, normally tends to force the dc locking position so that when he ie moved in such a manner as to o able jaw into closed position automatically act to lock the lever .50

l ii

tain the movable jaw in such closed position. Thus the clamping means may he held in closed position during the normal operation ot the loom.

cluitablc means are provided for unlocking the detent from its engagement with the lever 30 upon call for transfer. lln the. preferred embodiment otthe invention illustrated herein the dog carrying member 10 is provided with a laterally extending releasingarm 44 which has an otlset lower end 45 which underlies the extension -10 of the detent. When the dog is actuatmhnpon call for transfer, the pivotal upward movement o'l' the dog (ZLIUSGQ the offset end 45 of the releasing arm ll to engage the cam face 41 of the detent arm 40 and raises the latter, thereby causing the opposite arm 01"" said lever to remove itsshouldcrS-hl 't'rom engagement with the actuating lever 30. The spring- 3: thereupon swings the actuating lever about its pivot and causes the movable jaw 24 to be swung to open position. it will be noted that this opening movement oi the clamping" means occurs at the time the dog of the transfer is being raised into position to he struck by the hunter upon the lay and that, therefore, the clinnping means are opened before the lay reaches transferring position.

ln the present invention means are provided for closing'the clamping means inlmediatelv after. trans'ler is ettected and pre'terably while the filling carrier or bobbin is in flight from the shuttle to the box or container into which it is discharged. This is accomplished in the device illustrated in the accompanying drawings by a stud 4-6 which is carried by the transferrer arm and is so positioned that during the final trans'lcrring movement oi the transterrer arm the stud it) will engage the ollsct end 47 of the lever 30 and swing said lever about its pivot in such a manner as to move the movable jaw to closed position and permit the detent 37 to lock said lever in the manner heretofore described.

in thenormal operation of the loom the jaws of the filling cud clamping means are in closed position as illustrated in, Fig. When transfer is callodtor the rotation of the controller rod 16 causes the arm 15 to raise the arm l t on the shuttle t'eeler thereby acting, through the stud 13 upon the dog 11, to raise said dog in the path of the hunter 12. its the dog 11 is thus raised the end portion 45 ot' the arm ll, which is carried by said dog, engages the cam "face ll of thoarm ll) of the detent 37, raising the arm 40 and conselluently depressing the other arm of the lever, thus moving the shoulder 39 out of engagement with the end of the lever 30. As soon as this end of the lever is thus released the spring 35, acting upon the other arm of the lever 30, forces the same forwardly or toward the trout of the loom thereby acting through the spring connection 22? to swing the movable jaw 24 of the filling end clampingmeans into the open position illustrated in fig. 4. This action occurs before the lay reaches its beat-up.

During the latter portion ot the heat up of the lay the banter 12 carried by the lay engages the dog ll of the transterrer and rocks the translerrcr arm 6 about its pivot in the usual manner, thus arising the trans terrer head 7 to thrust a filling carrier or bobbin from the hopper into the shuttle. thereby ejecting the old filling carrier from the shuttle.

During the final motion of the transferring movement of the tiansterrer the stud 4-6 which is carried by the extension 9 of the trans'lerrer engages the oii'sct end 47' of the lever 30 and moves the same tor *ardly, thereby iswinging the opposite end of the lever 30 rearwardlv and causing the same. through the spring 3?. to swing the movable jaw E l into closed position.

it will be observed that the nuivable jaw 24- ot the clamping means is thus swung across the path of the filling end running from the discharged filling carrier immediately after the filling carrier has been ejected from the shuttle so that the filling remains under suilicient tension as it reels oil of the filling iarrier to enable it to be caught readily by the movable jaw of the clamping mechanism. inasmuch as the nu 'ahle jaw Q-l is closed against the stationary jaw 23 before the completion of the transferring movement of the trans-terror the clamping of the tilting end before the next pick of the shuttle is insured.

When the translerrer reaches the limit of its movement the stud 4-6 will have swung the end ot' the lever 30 sutliciently to enable the shoulder 39 oil the detent 3? again to engage the lever. 'lhe detent 37 is thus caused automatically to engage the lever by the action of the spring lly thus locking the lever 31) the filling end clamping" means is held in closed position until again released as above described upon a succeeding call for transfer.

it will be understood that the embodiment of the invention disclosed herein is illustra tire and not restrictive and that various changes in construction and arrangement oi parts may be made within the spirit and scope of the following claims.

Having thus described my inventioiu what it claim as new, and desire to secure by Letters Patent, is:
